A comprehensive treatment approach for young leachate landfill (YLL) from Fez City was investigated using an integral system involving aeration as a pretreatment before the binary oxidation process using hydrogen peroxide (HP)/persulfate (PS) as oxidants, in which UV-A irradiation and ultrasonic (US) are used as activators (HP-PS-US-UV-A). The initial treatment by aeration resulted in COD, color, and Abs
